Following on from my earlier post one of our team has come up with a simpler workaround.

What you need to do is run the 'Transaction Report'. I can't find it in the list of reports but if you run a trial balance and drill into the balance of the account you need, you can then change dates to those you require, in our case 1.8.2019 to 31.7.2019

If you can do this, as with all other reports, you can then customise the distribution accounts option to select all of the accounts you require.

I haven't needed to do this with classes as a further filter, so I can look forward to that!

Hope that helps.
